JAMES B. SEXTON, OF PELLA, IOWA.

WAGON-BRAKE LEVER.

SPECIFICATION forming part of Letters Patent No. 227,847, dated May 18; 1880'.

' Application filed November 20, 1879. i

To all whom it may concern:

Be it known that I, JAMES B. SEXTON, of Pella, in the county of Marion and State of Iowa, have invented certain new and useful Improvements in Wagon-Locks and Brake- Levers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to-the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a side elevation of my wagon-lock and brake-lever. Fig. 2 is an end view of the same, and Figs. 3 and 4 are detail views.

This invention relates to vehicle-brakes; and

it consists inthe improvements in the construction of the same, hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, A designates the double sector-rack, which is composed of the two rack-bars a a, having teeth in their upper edges, and secured side by side, so as to leave an intermediate way for the travel of the lower end of a brake-lever, B. This brakelever B is pivoted between the cross-bars O O of the sector-rack, and extends between the two rack-bars, so that all lateral play or Wabbling upon its pivot will be effectively prevented. The bar G extends only sufliciently far to form abearing for the pivot of the brakelever, while the bar (J extends from arm a to arm a upon its side of the sector-rack.

D designates the latch-lever, which is pivoted atlthe upper end of the lever-bar B, and E designates the gravity pawl or latch, which is pivoted at the lower end of the said leverbar, so as to engage with the double lines of teeth of the sector-rack, the said pawl and latch-lever being connected by means of a latchrod F.

The devices for connecting the brake-rod Gr with the brake-lever B are constructed as follows: Hrefers to a sliding sleeve, which is arranged upon the brake-lever; and I, a thumbscrew for securing the sleeve at any desired point upon the same.

K designates a platezformed with a sleeve, L, which screws upon the end of the brake-rod Gr,

, and, as herein illustrated, this ,plate is connected with the sleeve H by means of a pivot, M, which passes through an extended portion of the said sleeve.

In order to prevent the pivot fromworking out of its bearing in the sleeve, I pass a pin, N, through its end, whereby the parts will be properly held together during use. 7

In order to adjust the sleeve H upon the brake-lever so as to increase or decrease the leverage, it will simply be necessary to loosen it upon the lever by partially unscrewing the thumb-screw, and then slip it toward or away from the fulcral bearing of the brake-lever, after which the thumb-screw will be again tightened up. y

In order to tighten up the brake-rod so a to take up all unnecessary slack, I remove the pin N from the pivot of the plate K, and then disconnect this plate from the sleeve upon the brake-lever, so that it may be turned round sufliciently to screw up its sleeve upon the brake-rod, afterwhich it is reconnected with the sleeve, as before.

As herein shown, the sector-rack is connected with the side of a wagon by a bracket, and, when desired, this may be transferred from one side to the other of the wagon. In

to reverse the brake-lever, and hence I extend the bar 0 only part way between the ends of the rack-bars, so that a space will be left for the removal of the same after its pivot has been removed from the frame of the sector racks.

The advantages of my adjustable connection between the brakelever and brake-rod will be evident upon comparison with the old way, which usually consists in forming the brake-lever with a series of holes, through which the pivot of the connecting-yoke is passed. Under my improvement I am not limited to determinate distances of adjust went, but may adjust the sleeve to any desired degree, whether great or small.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a wagon-brake, the double sector-rack A, having downwardly-curved rack-bars a a, with teeth in their upper edges, and the brakelever B, extended between the two bars of the said rack and having a gravity-pawl arranged to engage with the same, substantially as herein shown and set forth.

2. The brake-lever B, in combination with the double sector-rack A, having the arms 0 O, which form a space for the removal of the brake-lever, whereby it may be reversed when the brake is changed. from one side of the wagon to the other, substantially as shown and set forth.

3. The plate K, having a sleeve, L, adapted to be screwed upon the brake-rod, and a pivot, M, detachably connected with a sleeve, H, upon the brake-rod, substantially as shown and set forth.
